<p>A rear projector, includes: a light source; an optical modulator that forms images through modulation of luminous fluxes coming from the light source based on image information; an image formation device provided with a projection optical device that enlarges and projects the images formed by the optical modulator; a reflective mirror that reflects the luminous fluxes as the images coming from the projection optical device; a screen on which the luminous fluxes are projected after reflected by the reflective mirror; and a box cabinet that accommodates the components of the rear projector. In the rear projector, the cabinet includes a first cabinet section that accommodates the image formation device, and a second cabinet section that is provided with the screen and the reflective mirror, the optical modulator is accommodated in a sealed space including a space of the second cabinet section, the second cabinet section includes a side surface on which the screen is provided, and another side surface that faces the side surface and is placed with an interstice from the reflective mirror, and the interstice is formed with a path through which air used for cooling the optical modulator circulates.</p> |
